Zhao Ying: Introduction to LED device standardization work

Zhao Ying, senior engineer of the Semiconductor Lighting Technology Standards Working Group, introduced the standardization of LED devices at the conference. From an in-depth and comprehensive report by Zhao Ying, we can know that the “Semiconductor Lighting Technical Standards Working Group” (hereinafter referred to as the Standard Working Group) was established in 2005, and the Secretariat was established at the China Electronics Standardization Institute. The standard working group is in the information. Under the leadership of the Ministry of Industry, research on the standard system of semiconductor lighting technology, propose national standards and electronic industry standard system, revision plan recommendations, organize the development of national standards and electronic industry standards, and organize participation in international standardization activities. It involves all parties involved in the production, learning and research of materials, chips, devices, modules, some applied products and test instruments in the semiconductor lighting industry chain.
The semiconductor lighting technology standards working group has developed two standards: power LED blank detail specification and semiconductor light-emitting diode test method. Semiconductor lighting terminology and definition, semiconductor light-emitting diode chip test method, power semiconductor light-emitting diode chip specification, low-power LED blank detail specification, semiconductor light-emitting diode product series spectrum, sapphire substrate for gallium nitride-based light-emitting diode, Standard for phosphors for semiconductor light-emitting diodes.
Research is being carried out: semiconductor light-emitting diode life test method, and radiation safety research of light-emitting diodes. Future work will focus on the performance specifications and test methods of LED modules and the development of standards for other products, such as: LED module performance specifications, test methods; performance specifications for medium and small size LED backlights; characterization and testing of chip "thermal characteristics" method.
With the support of the national ministries and commissions, I believe that under the joint efforts of all, the standardization of semiconductor devices and optoelectronic devices. The national standards and electronic industry standards for electronic devices will be gradually improved, which will play a positive role in the development of the entire industry.
